DiagnosticRecorderNode class

Constructor & Destructor Documentation

DiagnosticRecorderNode()

switchboard::DiagnosticRecorderNode::DiagnosticRecorderNode

(

const uint

sampleSeconds = 30

)

Creates a DiagnosticRecorderNode instance.

Parameters

sampleSeconds

The amount of audio to keep in seconds.

Member Function Documentation

createTap()

SingleBusAudioProcessorNode & switchboard::DiagnosticRecorderNode::createTap

(

const std::string &

name

)

Creates and returns a new SingleBusAudioProcessorNode to be added in an audio graph as a recording tap.

Parameters

name	Name that will be added to the recorded file name to identify the recording.

Returns

The new SingleBusAudioProcessorNode.

dump()

bool switchboard::DiagnosticRecorderNode::dump	(	const std::string &	recordingFilePath,
		Codec	format,
		bool	realtime = true )

Writes the last N seconds of recorded audio to multiple files (one for each tap).

Parameters

recordingFilePath	Final recording file path without extension.
format	Final recording file format.
realtime	If true then sample accuracy is guaranteed for the different taps, but the containing graph must be running.

Returns

True if file operation was successful.

process()

bool switchboard::DiagnosticRecorderNode::process ( AudioBus & inBus, AudioBus & outBus )

overridevirtual

Processes audio data from the given input bus and produces the audio output to the given output bus.

Should be overridden by subclasses.

Parameters

inBus	The input bus that contain the audio data.
outBus	The output bus which should be filled with the processed audio data.

Returns

True if audio was processed successfully, false otherwise.

Implements switchboard::SingleBusAudioProcessorNode.

setBusFormat()

bool switchboard::DiagnosticRecorderNode::setBusFormat ( AudioBusFormat & inputBusFormat, AudioBusFormat & outputBusFormat )

overridevirtual

Sets bus format.

Should be overridden by subclasses.

Parameters

inputBusFormat	The input bus format to set.
outputBusFormat	The output bus format to set.

Returns

True if the bus formats were set successfully, false otherwise.

Implements switchboard::SingleBusAudioProcessorNode.
